March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Locational Affinity Awareness for BAN Applications Submission 2 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Purpose • To describe the necessity of locational affinity awareness for the various BAN applications Submission 3 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Locational Affinity Awareness • Recognize the degree of affinity between two nodes in the locational point of view – according to the measured parameters related of the physical proximity such as distance, touch, direction, etc – It may take time in measuring these parameters to get a certain recognition level Submission 4 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Locational Affinity Awareness • Function – A kind of context awareness • Automatic connection setup • User select an appropriate recommended connection • Objectives – To lighten loads for connecting proximate BAN devices manually – Locational affinity to help context-aware services Submission 5 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Applicable Cases • Medical – Patient monitoring or examination [1] • Non-medical – E-charm [2] (personal item tracking) – Smart key – Game application – Social networking service Submission 6 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Technical Components • Connection setup • Parameter measurement – Encounter related – Distance – Direction • Privacy and Security (E. G. ) Locational Affinity = f (distance, direction, encounter) Submission 7 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Connection Setup Submission 8 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Connection Setup • Features – When two nodes encounter in the bodyaround range, the connection to exchange the temporary data should be established by the unconscious way • Methods – Neighbor node discovery – Fast hand-shaking Submission 9 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Measurement Submission 10 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Encounter related parameter • The ratio of encounter • The pattern of encounter • The type of encounter – Normal – Touch Submission 11 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Touch Awareness • Features – To recognize the close intimacy • the type of encounter (Normal, Touch) – Very powerful function for easy and intuitive connection setup of BAN devices • BAN system can distinguish the on/in-body node from the around-body node • Method – Human body communication Submission 12 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Distance Awareness • Features – The distance between two nodes is measured – The degree of affinity can be inferred from the measured distance • Method – Fine ranging technique Submission 13 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Direction Awareness • Features – Recognize whether the conversation is in the face-to-face condition or not • Methods – RF technology – Geo-magnetic sensor – Vision/image processing – Others? Submission 14 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Privacy and Security Submission 15 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Privacy and Security • Automatic connection setup for the locational affinity awareness is not secure • Authentication should be done for some use-cases – An application considering user privacy – a group-aware application – making a random encounter into authenticated one • Identification may be inevitable to get higher security Submission 16 Seung-Hoon Park, Samsung

March, 2008 doc. : IEEE 802. 15 -08 -0146 -01 -0006 Conclusion • Locational affinity awareness is required for some BAN applications • Required Techniques – Neighbor node discovery & hand-shaking – Ranging – Human body communication – Authentication or identification Submission 17 Seung-Hoon Park, Samsung
